Transformations photochimiques d'endoperoxydes derives d'hydrocarbures aromatiques polycycliques V. Cas de I'endoperoxyde de rubrene: formation d'un nouveau type de photo-isomere

Photolysis in benzene at long wavelengths (λ>=420 nm) of rubrene endoperoxide. 11 affords mainly the bicyclic acetal 18, accompanied by the rubrene "iso-oxyde" 22 and by a new isomer: 11b-phenoxy-5a,6,11-triphenyl-5a,11b-dihydro-naphto cyclobutabenzo(b)furan 23, the structure of which has been established by 13C NMR.These various compounds result very likely from subsequent isomerizations of the two unstable meso-diepoxydes 13 and 14 arising first in the process.Moreover, diepoxide 14, precursor of 22 and 23, has been trapped by N-methylmaleimide as adduct 15.
